Get her tuned.

Theres alot more than throwing a supercharger on a car than meets the eye.
First, a few bolt ons isnt gonna make much of anything "scary fast."
But heres some things to do to make your pony run like it should-

1) injectors
2) Tune the damn thing
3) running forced induction usually works lots better with different pistons, Dished are really meant for just that.
4) final drive gear, i think those from the factory where somewhere along the lines of either a 3.27, or a 3.08... 3.73 should be the best option for street/strip
5) camshaft.. It can do wonders, trust me.

You gotta think deeper than top end.
